To all lwhom it may concern:

tion of the' said invention, reference being had to theannexed drawing, making' part of this specification, wherein Figure lis a vertical longitudinal section of my brushing or finishing-machine;

' Figure 2 is a plan of the same; and

Figure 3 is an elevation of the gearing and mechanism for actuating finishing-brush. N

Similar marks of reference denote the same parts. In manufacturing hat-bodies, itis necessary to felt or full the conc, to give to it the necessary firm character. After this is done, the brushing-operation is performed on those hat-bodies that are to have a raised nap. This brushing-operation has heretofore been performed by hand, while the hat-body is wetted with hot water. This operation is slow, expensive, and very exhaustive to the operatives, the object of the brushing being to raise the nap, and smooth and polish the bres on all sides.

My invention is primarily intended for brushing up the nap in hat-bodies, and consists in mechanism for giving the brush or polisher a motion corresponding to that by the human hand and arm, so that the brush or polisher can be revolved in a large or small ellipse, and in either direction, and'supplied with water; so

. that the hat-body will be finished in the most perfect manner by the brushing and polishing.

In the drawinga is the bed of the machine, mountedi on legs b b,

and carrying the vat c, in which the hat-bodies are placed, and allowed to soalr in-'hot water,andthen removed, o ne at a time, to be operated on in the machine.

d is a bed, made for the reception of the`article to be'operated on.

This is mounted upon a vertical shaft, e, to .which a treadle, f, is attached, so that the bed (l and hat-body or other article thereon, can be pressed against the brush or polisher, as the same is moved, as hereafter indicated.

I have representedthis bed l as made with a perforated surface, 2, over a box, 3, from which the water is led by a pipe, 4, but this is only specially available where hot water is employed in brushing and finishing the hat-body and similar articles. This same device might be used in supplying steam. below the article,

This crank-pin i is movable in a slotted T-head, m, to the shaft n,.so that the circle described by said crank-pin cau-be increased or lessened, and, by con-v sequence, the movement of the brush or polisher h enlarged or diminished.

The shaft n is driven, from the shaft p, by the wheel q or fr acting upon the wheel s. I prefer that these wheels be formed with bevel or mitre-faces, and there may be gear-teeth on said wheels, but usually the friction will be sufiicient. 4

The springs 5 5 serve to keep the wheels q lr s. in contact. The wheels q r, however, are loose on the shaft 1), and, according to which of said wheels q or fr is coupled with the shaft p, by sliding the coupling t,

either one direction or the other, by the shaft n, and

In order to vary the extent of motion given to the brush, and to render the same more or less elliptical, I adjust the fulcrum-stud Z by the screw c, the elliptical movement beingr increased by moving the fulcrurn l towards the shaft n, or lessened by the reverse moyement.

The brush or polisher h, when used for nishing hatbodies, is to be set into the .bottom of a hollow box, h', into which hot water is to be introduced by a flexible .jor polishing, is materially lessened, and the operations performed resemble those done by hand.

This mechanism might be applied to any other character of polishing and finishing that requires the peculiar-ity of motion set forth, vbut the same is especially adapted to brushing and finishing hatbodies, Where the fur requires to be brushed' on one side, and then the lmotion reversed, to brush on the other side ofthe nbre, and, lat the same time, a yielding pressure maintained of the brush upon the material.
